AMD Ryzen Z1 GPU vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Verdict

The recorded data places the AMD Ryzen Z1 GPU and the NVIDIA GeForce RTX 5070 Mobile in completely different performance classes. The RTX 5070 Mobile holds the 75th percentile among all GPUs in the database, while the Ryzen Z1 GPU sits at the 50th percentile. The NVIDIA part has an average benchmark score of 29928, whereas the AMD part has an average benchmark score of zero, indicating no recorded benchmark runs in the database for the Z1 GPU. The RTX 5070 Mobile delivers roughly 4.7 times the FP32 throughput, 5.1 times the texture rate, and 3.4 times the pixel rate of the Ryzen Z1 GPU. The Ryzen Z1 GPU is positioned as a low-power embedded console-oriented solution with a 30 W TDP, while the RTX 5070 Mobile uses 50 W and targets portable gaming systems. Benchmark data overwhelmingly favors the NVIDIA part; the Z1 GPU has no wins recorded in head-to-head comparisons, and the RTX 5070 Mobile has no losses. The data indicates that the RTX 5070 Mobile is the only reasonable choice for compute-heavy tasks, while the Ryzen Z1 GPU offers a minimal-power alternative for constrained environments where its lower TDP is the primary advantage.

Architecture Differences

The two GPUs share TSMC as their foundry, but they diverge in nearly every architectural detail. The AMD Ryzen Z1 GPU uses the Phoenix chip on the RDNA 3.0 architecture, built on a 4 nm process. It contains 25,390 million transistors on a 178 mm² die, resulting in a transistor density of 142.6 million per square millimeter. The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip on the Blackwell 2.0 architecture, built on a 5 nm process. It contains 21,900 million transistors on a 181 mm² die, giving a transistor density of 121.0 million per square millimeter. The AMD chip packs more transistors into a slightly smaller die, but the NVIDIA chip uses its larger area with a different execution structure.

The NVIDIA part includes 4608 shading units, 144 texture mapping units, 48 raster output units, 36 RT cores, and 144 tensor cores. The AMD part has 256 shading units, 16 TMUs, 8 ROPs, and 4 RT cores, with no tensor cores listed. This structural disparity explains the massive difference in raw throughput. The RTX 5070 Mobile reaches 13.13 TFLOPS of FP32 performance with 1:1 FP16 ratio, while the Ryzen Z1 GPU delivers 2.560 TFLOPS of FP32 and 5.120 TFLOPS of FP16 at a 2:1 ratio. The NVIDIA architecture processes FP16 at the same rate as FP32, whereas the AMD architecture halves its FP16 rate relative to FP32.

Clock behavior also differs significantly. The AMD GPU runs at a base clock of 1500 MHz and boosts to 2500 MHz, while the NVIDIA GPU runs at a base clock of 907 MHz and boosts to only 1425 MHz. Despite the lower clocks, the NVIDIA part achieves far higher throughput because of its much wider execution resources. The memory subsystems are entirely different as well. The Ryzen Z1 GPU uses 16 GB of LPDDR5 on a 64-bit bus with 51.20 GB/s of bandwidth, while the RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s of bandwidth. The NVIDIA part has 7.5 times the memory bandwidth despite having half the capacity.

The bus interface differs too. The RTX 5070 Mobile connects through PCIe 5.0 x16, while the Ryzen Z1 GPU lists no bus interface in the database. Display outputs also differ: the RTX 5070 Mobile is marked as portable device dependent, and the Ryzen Z1 GPU has no outputs at all. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

Where Each One Wins

The benchmark data shows a one-sided comparison. The RTX 5070 Mobile has wins across every recorded test, and the Ryzen Z1 GPU has no recorded benchmark scores at all. In the nine benchmarks listed for the NVIDIA part, scores range from a low of 93 in Passmark DirectX 12 to a high of 122238 in Geekbench OpenCL. The Geekbench Vulkan score reaches 116960, and the Passmark GPU Compute score reaches 8279. The Passmark G3D score is 20355, while the Passmark G2D score is 896. The DirectX 9, 10, and 11 scores are 214, 129, and 192 respectively.

The Ryzen Z1 GPU cannot claim a single benchmark win because no benchmark data exists for it in the database. Its only recorded advantage is structural: lower power consumption at 30 W versus 50 W, and double the memory capacity at 16 GB versus 8 GB. The database shows winsA as 0 and winsB as 0 in head-to-head benchmarks, meaning no direct comparison tests are recorded. The RTX 5070 Mobile's nearest rivals provide context for its standing. It sits within 0.1% of the RTX 3070 Ti, 0.5% ahead of the RTX 2080 Ti, 0.6% behind the RX 6800, and 1.7% behind the RX 6700. These rival comparisons suggest the RTX 5070 Mobile performs in the upper mid-range tier of desktop GPUs from previous generations, despite being a mobile part.

Head-to-Head Benchmarks

No direct head-to-head benchmark results exist in the database for these two GPUs. The winsA and winsB fields both read zero, and the headToHeadBenchmarks array is empty. However, the RTX 5070 Mobile has a complete set of nine recorded benchmark scores, while the Ryzen Z1 GPU has none. This absence of data for the AMD part means every available comparison must rely on the NVIDIA part's raw scores and its position relative to other GPUs.

The RTX 5070 Mobile's strongest recorded result is the Geekbench OpenCL score of 122238. Its Vulkan score of 116960 is nearly as high. These two scores indicate strong general-purpose compute performance. The Passmark G3D score of 20355 and the Passmark GPU Compute score of 8279 provide additional evidence of capable graphics and compute throughput. The DirectX-specific Passmark scores are lower: 214 in DirectX 9, 129 in DirectX 10, 192 in DirectX 11, and 93 in DirectX 12. The G2D score of 896 reflects 2D rendering performance, which is a separate workload from 3D gaming.

The Ryzen Z1 GPU has no comparable numbers. Its theoretical specifications, however, show the scale of the gap. The RTX 5070 Mobile delivers 13.13 TFLOPS of FP32 performance versus 2.560 TFLOPS for the Ryzen Z1 GPU, a factor of 5.1. The texture rate difference is similar: 205.2 GTexel/s versus 40.00 GTexel/s, a factor of 5.1. The pixel rate difference is 68.40 GPixel/s versus 20.00 GPixel/s, a factor of 3.4. The RTX 5070 Mobile has 36 RT cores versus 4, and 144 tensor cores versus none. Memory bandwidth favors the NVIDIA part by a factor of 7.5.

The nearest rival data for the RTX 5070 Mobile places it in a tight cluster with older high-end desktop cards. Its average score of 29928 is within 1.7% of all four listed rivals. The closest rival is the RTX 3070 Ti at 29945, a difference of only 0.1%. The RTX 2080 Ti trails by 0.5%, and the two AMD desktop cards lead by 0.6% and 1.7% respectively. This clustering indicates that the mobile RTX 5070 performs at the same level as those desktop parts, which is notable for a 50 W mobile GPU.
